What happens to bandwidth when damping is increased?

Explanation:
Increasing damping broadens the transducer’s resonance, so the bandwidth grows. Dampening causes energy to be lost each cycle, lowering the quality factor (Q) of the resonator. Since bandwidth is roughly the center frequency divided by Q, a lower Q means a larger Δf, i.e., a wider bandwidth. In practice, a heavily damped transducer emits a wider spectrum, while a lightly damped one has a narrower spectrum.
